Fig. 12 is a Hence it will be seen that when the vessels are in the position illustrated in the drawings the supply of liquid will pass from the tank B and through the induction pipe or channel (1 into one of the discharge-vessels E, that is coincident with said pipe or channel d, and when by the rotation of the holder E the vessels E and E are rotated, so as to bring the vessel. E coincident with the discharge pipe or channel cl, the supply of liquid within such vessel E will be discharged through said pipe or channel.

With the discharge pipe or channel (1 is preferably connected a cooling-pipe F, that extends, by preference, in coiled form into an ice-tank G, the ice preferably resting upon a tray g and the drip-water being carried away from the bottom of the ice-tank by a suitable pipe g. The opposite end of the cooling-pipe F is connected to a spout or faucet F, leading through the front of the inclosing casing, and from this spout will be received the liquid as it is dispensed.

By preference the front of the casing is provided with a tray H, having a false bottom h, on which will rest the glass to receive the liquid, and the bottom of this tray H is furnished with a discharge-pipe h, whereby the waste-water will pass into the ice-tank G, whence it will. be discharged through the pipe g.

In order to effect the movement of the discharge-vessels E and E, I prefer to employ the mechanism next to be described. The central portion of the holder E is bored out to receive an operating-rod I, the opposite end of this rod extending through the plate K at the front of the inclosing casing and there provided with a handle 2', whereby the rod can be conveniently turned. Through the lugs 2 of the cover-plate D extend the tierods 3 of the cover-plate D, the ends of these tie-rods being suitably headed and provided with nuts to secure the parts firmly together. Upon the operating-rod is mounted a delivery-chute L, provided with a channel or runway L, adapted to be brought coincident with a slot is in the front plate K. On the rod I is also mounted a coin-carrier M, this carrier being fixed to the rod I to be turned therewith and being provided with a seat on to receive a suitable coin or check by which the apparatus is to be rendered operative. The coin-carrier M is preferably formed with a long hub m, that passes through a fixed plate N, the ends of which are perforated to receive the tie-rods 3, and upon the hub 77? of the coin-carrier is placed the coiled spring 0, one end of which is connected, as at 0, to the hub of the coin -carrier, while the opposite end is connected to the plate N, so that this spring tends to return the coincarrier to the normal position whenever it is moved therefrom by the turning of the rod 1. The fixed plate N is formed with a slot n opposite the seat of the coin-carrier, but the edge of the plate Noverlaps the seat m of the coin-carrier, so that if the coin be not of the required thickness the inclined bottom of the seat m will cause the coin to roll through the slot at of the plate, whereas if the coin be of proper thickness the overlapping edge of the plate N will serve to retain the coin within the seat of the coin-carrier. To the holderE by which the vessels E and E are carried, is fixed a ratchet-wheel P, with the teeth of which engage the check-pawl 19, that is pivoted upon the tie-rods 3, this pawl serving to guard the ratchet-Wheel P, and consequently the vessels E and E, against backward movement. To the face of the ratchet-wheel P is also connected the coin engaging dogs or pawls R and R, each of these dogs or pawls being pivoted, as at r, to the ratchet-wheel and being provided with a notch 'r', with which the edge of the coin will engage. Upon the face of the ratchet-wheel P and opposite the notches r of the pawls or dogs R R are formed the lugs 19', the purpose of which will presently appear. Suitable springs 73, attached to the face of the ratchet-wheel P and encircling the pins 7*, upon which the pawls or dogs R are carried, force the dogs against the rim of the coin-carrier and hold the pawls or dogs in proper position to engage the coin within the seat of the coin-carrier. To the fixed plate N is attached a releasing-arm S, having an inwardly-proj ecting pin 5, adapted to contact with the inclined ends 4' ofthe dogs or pawls R R, this arm S being preferably connected to the fixed plate N by a set-screw s, passing through a slot 3 of the releasing-plate, so that the position of the releasing-plate can be adjusted to accurately time the release of the coin. Upon the fixed plate N is also held a check-pawl T, preferably of spring metal and connected to the plate N by a set-screw t, that passes through a slot 25' of the pawl. The free end '6 of the check-pawl T is bent inwardly and inclined, as seen in Fig. 3, and by preference the edge of the pawl T bears against a pin 25", projecting from the face of the plate N.

From the construction of parts, as thus far defined, the operation of my improved apparatus will be seen to be as follows: If a coin is inserted through the slot of the plate K, it will roll down the channel L until it falls into the seat at of the coin-carrier M. If the coin be of proper thickness, it will remain within the seat of the coin-carrier; but if it be thinner than a coin of proper denomination it will pass from the seat of the coincarrier through the slot n of the fixed plate N and over into a tray or coin-box W Within the main casing A. hen a coin of proper denomination is thus within the seat of the coincarrier, its upper edge will project slightly above the seat of the coin-carrier, and if now the handle 2' of the rod I be turned the coincarrier will be rotated and will carry with it the coin until the coin rides against the lower edge of the pawl ordog R, slightly lifting this dog against the force of its spring until the edge of the coin passes into the seat or notch "r" of the dog. The continued turning of the handle 1' and rod I and of the coin-carrier will by reason of the engagement of the coin with the pawl or dog R cause the rotation of the ratchet-wheel P and of the vessel-holder E and vessels E and E until the vessel E, which is full of liquid, comes coincident with the discharge-channel d, permitting the liquid to pass into the cooling-pipe F. This discharge of liquid into the cooling-pipe F will force the liquid previously delivered into said pipe to pass therefrom by way of the spout or faucet F" into a suitable glass or receptacle. When the coin-carrier, the ratchet-wheel P, and the vessels have nearly completed their partial revolution incident to the turning of the handle i and rod I, the inclined end 4" of the pawl or dog R, that is in engagement with the coin, will contact with the pin 3 of the releasingarm S, and will be forced inward a sufficient distance to cause the opposite end of the dog or pawl R to pass from engagement with the coin, thereby permitting the coin to fall from the seat of the coin-carrier into the tray W. The check-pawl T will prevent the backward movement of the coin with the coin-carrier, and will cause the coin to be more certainly thrown from the seat of the coin-carrier as the latter is returned by the coiled reactionspring 0 to its original position. It is manifest that as the coin-carrier M is thus returned by the coiled spring to its original position the pawl p in-engagement with the ratchet-wheel P will prevent the backward movement of the ratchet-wheel and of the vesselholder and vessels connected therewith. As the vessel E is thus turned to position to discharge its contents, the vessel E will be brought coincident with the ind uctionchannel d and will receive from such channel a Supply of liquid in readiness to be discharged when the coin-carrier is again operated. It will be observed that the coin-chute L is mounted loosely upon the shaft or rod I; butthe extent of movement of this coin-chute is determined by the lugs 10 on the inner face of the front plate K, and a weak spring V, that has one end connected to the fixed plate N, bears with its opposite end against the runway L of the chute, tending to force this chute forward when the coin-carrier with a proper coin therein is moved in forward direction. Hence when the coin-carrier is so moved the chute L is shifted under the action of the spring V, so as to close the coin-slot In of the front plate K, until the coin-carrier is returned to its normal position by the coiled reaction-spring 0, when a pin :0 upon the hub m of the coin-carrier will engage with a pin w, projecting from the chute L, and cause the chute to be shifted backward until its runway is again coincident with the slot is of the front plate K.

It is manifest that the details of construction above set out may be varied within wide limits without departing from the spirit of my invention, and that certain features of my invention may be employed without its adoption as an entirety either in connection with liquid-dispensing apparatus or in connection with coin-controlled apparatus designed for other purposes.
